To all whom it may concern; p

. Be it known that l. ARTHUR lll.' Bion, a .subject ofthe King of England. i-esidinglatl London. in the Province ot' Oiitario, Can-- ada, have :invented certain new .and usetul Improvements in Gas-Regulating Valves, ot

ence being had therein to the accompanying .drawings4 This invention relates to an improved gals regulating vvalve and its object visto prolvid-e a simple, cheap and compact construcl tion whichi'is 'so made that it may be quickly and easily adjusted -to regulate the volumeandspe'cd l'or flow of the gas, to'niaintain perfect combustion. and when the 'device is incorporated in a --gas stove', or similar device to. prevent 'a back flash'andconsequcnt noise Tothese ends Vtheinvention 'consists in th'e.

Y matters hereinafter set forth and more pargitudinal vertical section throughthe same.A

.30 right.l angles to the gassupply pipe with-its ticularly pointed out` in the cl-a`inis"ret'er .ence'beinghad to the accompanyingdrawingin which- Figure 1v` is `,a side. elevation 'of -a device "embodying the invention; and FigQ-a lon- I In 1 ofthe drawing 10 indicates a suitable gas supply pipeffndjlil a "Bunscn tube' forming a gas mixing chamber at receiving end -at a short distance therefrom. The regulating valve embodying-'this inve-nL tion is. supported by' the piped() with its discharge'nozzl'ii'i alincinent with and adjacentitii the openend of the tube.

'-Thefregulating valveconsists of a casing 12 having a laterally extendingexternall screwthre'aded nipple 1 3 to engage. a screw# threaded opening-in the 'supply pipe 1 0 or other suitable' connection foisupplying gas to thevalve. 'A main supplypassage 14; eX-' tends horizontally 'through 'the nipple 13 and casing and longitudinallyv through a' tubular arm 1` which extendsV horizontally from, the .side of the'casing 'opposite'the nippel 13. The casing is also formed with' a vertical tapered b ore forming a seat tor a plug valve 16 `of the usual `construcnon having an vupwardly extending endportion to which is secured in any suitable mannera 'laterally extending handle- 1T 'for' turningA the plugin its seat. The plug is limited inits turning movement by means of a pin 18 carried by the upper end of theplug and engaging a notch 19 in the-upper .end of the;

casing 1Q. .The plug is formed with a transverse bore 'or passage Q0 to register is also bored longitudinally inward from its lower end and internally'-screwthreaded at.r said eiidto vreceive an screwthreaded stein 21 having an upper reduced end 4portion 22 litting within port-ien ot' thes'tein is formed With a deep wardA ,fi-cm one side ofthe stem to a point -beyond its longitudinal axis. This notch 'is located opposite the main gas passages() that by turning the stein within its bore. the

firmly seated in thecasing.

The tubular a'i'in or nipple 15 is externally 4portion of itsI length adjacent to the 'screw threads and further reduced-in diameter at its 'outer end. The bore of the .nipple is ing an axial discharge openingtor the 14. A lsleeve 27 having an internal screw thread to engage the .screW thread ot the nipple by turning the same and the bore of 'the sleeve is reduced in diameter toward its outer end forming a shoulder '28 to oppose a similar shoulder 29 formed upon the nipple by the reducing in diameter of the outer end.

adjacent to Ythe screyvthreaded port-ion of the nipple and intermediate its length and a similar ,space 31 is provided between the outer reduced end of the nipple. and' 'the ,.sleeve, theoiiter end o the nipple being of tlesser;4 diameter 4than the A smallest internal with the inain supply passage 14s and.

externally the inner end of the borev and extending across the main passage' 11; rlhis upper end notch er cut away' portion :23 vextending in-' side of the stein opposite the notch may be brought across the passage as showny in Fig.-

end of the' stem ,to hold vthe plug .valve 1G screwthreaded adjacent to thecasin'g 1Q and' is reducedin diameter through a middle closed atits extreme end byl a disk 25 hai-4 cscape of gas from tlie-, inat 'supply passageof the nipple.' A space or'chamber 30- is` thus formed between-the nipple and sleevel nipple is adjustable longitudinally uponl thc..

' ing into the chamber 30 and providing comv through the narrow passage 31 where it will lchamber 30 and space 81 is opened or- 'may be acegurately regulated by turning the diameter of the sleeve. A port or opening 32 1s provided in the side of the nipple openmunication between said chamber and the main gas passage 14;. By adjusting the sleeve upon the nipplejthe shoulder 28 of the sleeve is thus moved toward or from the. shoulder 29I on the nipple and the passage or space around the nipple formed by the closed or choked by the bringing' of the shoulder 28 nearer to or farther from the shoulder onthe nipple.

The volume of gas passing through ,the valve may be accurately regulated to suit,l the conditions of supply, by means of the stem 21, said .adjustment being a permanent adjustment -as the same is carried by the valve plug and turns with it when the plug is turned lto shut off or turn on the supply of gas., The velocity with which the gas will be discharged through the opening 2G in thel end of themain supplyI passage sleeve 27 'to adjust the shoulder 28 toward or from the shoulder 29 on the nipple and 1 permit a greater or lesser proportion of-gas passing through the main passage to escape laterally throughthe porty 32 into the chamber 30 around the nipple and pass out be carried into the end of the mixing tube 11 by the velocity of the stream of gas issuing from the discharge opening 26. The proper volumeV of gas may thus be discharged through the nozzle at exactly the proper velocity to give the best results and prevent any back flashv through the Bunsen tube. The choking of the auxiliary passage or outlet for tlief gas around the nipple at a distance from the discharge end of the nipple prevents any disagreeable noise whiehmight ctherwisebe caused b v the issuing of the gas through a contracted discharge end, and causes the gas to issue from the nipple with a smooth even flow..

Obviously, changes in the details of con` struction may be made without departing from the spiritof my invention and I do not' care to limit myself to the particular, form or arrangement shown.

Having thus fully described my invenL tion what I claim is l.4 The combination of a nipple havinglan outer end portion of uniform cross-sectional the sleeve;

diameter and formed with a main gas passage opening through said end, and a sleeve' f ladjustable upon said nipple having a bol-e 5 of uniform cross-sectional diameter extending inwardly from' one end, into which bore said end portion of the nipple projects with a space between said sleeve andI nipple forming an annularpassage of uniform crosssectional diameter open at its outer end and communicating at. its inner end with said main gas passage, said sleeve being inter nally formed to regulate the flow of gas into said annular passage by the adjustment of 2. The combination of a nipple having an outer end portion of uniform lcross-sectional diameter and formed with a main lgas'passage opening through said nipple anda lateral opening, a sleeve adjustable 'upon said nipple having a bore 0f uniform cross-seetional diameter extending inwardly from one end into which bore said end portion of the nipple projects with a space between said sleeve and nipple forming an annular passage of uniform' cross-sectional' diameter open at its outer end, andan annular internal lshoulder on the "sleeve at. the inner end of its end bore to oppose a portion of.the nipple and regulate 'the flow of gas into Said annularpassage when said sleeve is adjusted. v 3. The combination of a'nipple having an outer end,portion of uniform cross-sectional diameter and a screwthreaded portion vof greater diameter than the end portion, said nipple being also forniedwith a mainv gas passage extending axially therethrough and having an opening in `its-side, a thin wall Clo-slug the outer end of the mam gas pas-` sage through the nipple formed withf= axial discharge opening and 'having an inner the passage, a sleeve internally screwthreaded to engage -the screwthread of the nipple and formed with a, bore extending inward from its outer end lof uniform crossseetional diameter and' into which bore said end portion ofthe nipple projects with a space between said sleeve and nipple forming` an annular passage of uniform crosssee tional diameter open at its outer end. an annular internal shoulder on the sleeve at the inner end of the said end bore. and an annular shoulder on the nippleat the inner end of the end portion -of the nipple. said. shoulders beingv adjusted toward each other by the turning` of the sleeve to restrict the flow of gas from the main gas passage through the opening in the side of .the nip-v ple into .said annular'passage around the end portion of the nipple.
